Abstract
A calculation is facilitated for y[i]=q[i]×mod(p−1) which is required as an intermediate value when calculating intra-row permutation pattern U[i][j], which is a parameter for use by an interleaver for on a turbo code defined in a standard 3GPP TS25.212 of IMT 2000, from prime number p, base sequence s[j], inter-row permutation pattern T[i], and prime number sequence q[i]. First, index i and variable div are initialized to zero. When q[i]≧div+p−1, p−1 is added to the value of div. When q[i]<div+p−1, y[i] is calculated in accordance with y[i]=q[i]−div. Indexis incremented and the foregoing processing is repeated untilreaches R.
